Even if you do not like to read manual, please read this section.
This procedure is very important, even if you do not like to read manual. Please read
this section. After you connected up the system, you are ready to set the initial set up
for every input channel, the matching of every input trim to the signal source is crucial.
Every detail will affect the final output of the mixer. Basically, the input sensitivity
adjustment, channel fader, groups and output fader is the main factors. You should try
to set only as much microphone trim as required to achieve good balanced between
signals. It the input gain is set too low, you will not get enough gain on the faders to
push the signal up to adequate level, if the input gain is set too high, the channel fader
will need to be pulled down in compensation, but leave the greater risk of feedback
because a small fader movements will have a very significant effect on output level.
Certainly, the limited fader travel path will not successful in the mixing procedure.
Please use the following set up procedure, do not use the old way: turning the output
up until they clip and then backing off
Follow the procedure for each channel in use
Set all faders and gain controls all the way off.
Phantom powered microphone should be connected before the+48V is switched on.
Set power amplifier level to 70
％
.
Set the CTRL RM level and Headphone level to about 50%.
If you want to hear what you are doing later, plug your headphone into the phone
output socket
，
or hook up your control room amplifier system to the Control Room
outputs.
Set EQ control at center position.
Set PAN and BALANCED knobs at center position.
You need a headphone to continue.
Apply a typical performance level signal monitoring the level on the LED meter.
Adjust the input gain until the meter show in the amber section with occasional peak
to the first red LED at maximum source level. This allows enough headroom to
accommodate peak and the maximum level for normal operation; you can listen to
them through your headphone.
For +4 line level audio signals, slide the+41-10 switch to +4.
For -10 sources. slide the +4/-10 swatch to -10.
For microphone source, the gain control adjustment will depend on what kind of the
microphone you use
，
normally turn the gain clockwise around 2-3 o’clock. But please
ask the singer to perform alive, do not whisper. If they did not wake up while you are
doing the sound check when they are back to alive, you might drive the mixer overload
or produce the feedback, because you Set the gain too high during the initial set up.
Most often mistakes in audio installation are incorrect and deflective audio
Repeat this procedure on every other channel, when more channels are added to the
mixer. the meters LED may move up to the red section
。
adjust the overall level using
the Pilaster faders if necessary.
